how should I apply this part to the script?

The “Delete files or directories” selection should prompt for a list of files or directories to be deleted. The script asks user for confirmation before deleting a file or a whole directory. The script must perform reasonable argument validation.

I tried to read the list of files and directories in a string but it is pretty hard to split the string based on space and put them in an array and then check them one by one and delete them. Also I was thinking to run a while loop to ask user to enter the name of file and then delete it and again repeat the job but it is not a nice way.
would you give me some clue?

Code:

#!/bin/sh
clear
	echo "\t `date "+%d/%m/%Y"`"
	echo "\t Hostname Machine: `hostname`"
	echo "\t user: `whoami` "
	echo "\t M A I N - M E N U"
	echo "\t 1.Copey Directory Tree"
	echo "\t 2.Delete Files or Directories"
	echo "\t 3.Output Information"
while true ; do
	echo -n "\t Please enter an option [ 1 - 4 ] : "
	read opt

	case "$opt" in
		1) echo "Enter the source of the files and destination for copying "
                   read src dest
                if [ -n "$src" -a -n "$dest" ]
		then
			if [ -d "$src" -o -f "$src" -a -d "$dest" ]
			then
			cp -r "$src" "$dest"
			else
			echo "Enter the valid file or directory addresses" 
			fi
		else
		echo "please enter valid address as a source and destination to copy the files "
			fi ;;
		2) echo "enter the name of files want to be deleted"
		read files
		for f in "$files"
		do
		echo "$f\n"
		done  
		 ;;

		3) echo "\t the number of possible users on the system: `cat /etc/passwd |wc -l`"
		   echo "\t the number of current user on the system : `who | wc -l`"
		   echo "\t the number of processes running: `ps -e | wc -l`"
			 ;;


		*) exit ;; 
	esac
done
